That I regard as new, and desire to secure by Letters Patent, isvr 1. Aneedle-threader, comprising a shank carrying an upper guide-prong and alower guide-prong which lie in diilerent planes to ada t thern toeinbraee a needle, a threadhoo projecting into the eroteh between saidguide-prongs, and a rearwardly extending guard crossing the spacebetween the horizontal planes of said guide prongs, whereby the threadmay be passed beneath the upper guide-prong and above the lowerguide-prong, then moved, while ridingr on said guard, to pass saidthread-hook, and finally retracted and guided by said guard intooperative engagement with said thread-hook.

2. A needle-threader, comprising a nieinber equipped with upper andlower guideprongs, one of said prongs carrying a rearwardly and upwardlypointed guard-arm, Said guide-prongs lying on opposite sides of aneedle-reeelving space, and a thread-hook extending into said space andlying between the upper guide-prong and said guard-arm, for the purposeset forth.

3. A needle-threader, comprising a sheet- Inetal inelnber having themetal split longitudinally at one end and the fureations struck inopposite directions to alord guidebetween said guard-arm and said upperfure ation 5. A threader, comprising a sheet-metal member formed with.oppositely struek upper and lower fureations and with arearwardlypointed guard-arm, and a separately formed thread-hooksecured` to the shank of said sheet-metal member and having itsoperative end lying between said guard-arm and the opposed fureation,for the purpose set forth.

6. A threader, Comprising a shank and upper and lower fureations carriedthereby and separated by a needle-receiving space, and a thread-hookhaving its operative end extending into the eroteh between saidfureations, the extren'lities of the l'ureations projeeting past the oJerative end of said thread-hook, whereby the thread may be drawnbetween the adj aeent edges of said fureations and earried past theyprong of the thread-hook and then retraeted and carried into operativeengagement with the tlnead-l'iook.

7. A threader, comprising a shank and two lureations` carried therebylocated on opposite sides of a vertieal plane to provide bel tween thema needle-reeeiving spaee. the 1 lower surface of one fnreation beingnear the level of the upper surt'aee of the other fureation, one of saidfureations being longer than the other, and a thread-hook having itsoperative end extending into the eroteh between said l'ureations,whereby the thread may be drawn between the adjaeent edges ol' saidl'urcations and earried past the prong ot the thread-hook and thenretraeted and earried into operative engagement witlle the thread-hook.
